Embodiment Construction

[0021] The present invention will be described in detail below with reference to the accompanying drawings.

[0022] refer to figure 1 There is a bag body 3 between the upper cover plate 2 and the lower cover plate 4 of the present invention, and an airbag shock absorber 1 is formed between the bag body and the upper and lower cover plates. The airbag shock absorber is installed between the foundation and the middle mass 5, and the upper shock absorber 8 is installed between the middle mass and the electromechanical equipment 15; the air pipe connected with the airbag air nozzle 14 passes through the upper cover plate and communicates with the airbag shock absorber . The charging solenoid valve is connected to the compressed air source. The feedback control system is integrated on the intermediate mass. The lower cover is mounted on the base 16 .

[0023] The airbag shock absorber 1 is a bladder-type structure, a membrane-type structure or a cylinder-piston-type structure....

Abstract

The invention discloses an integrated adjustable double-layer damping module. An airbag damper is mounted between a base and a middle mass; an upper-layer damper is mounted between the middle mass andelectromechanical equipment; the middle mass is provided with an additional mass block or a vibration absorber; the airbag damper is connected with a pressure sensor, a deflation electromagnetic valve and an inflation electromagnetic valve through air pipes; a controller is connected with a displacement sensor, the pressure sensor, the deflation electromagnetic valve and the inflation electromagnetic valve through cables to form a feedback control system; and the feedback control system is mounted on the middle mass. With the height between the electromechanical equipment and the base as a control target, and in reference to in-bag air pressure of the airbag damper, the height precision is controlled. The airbag damper is adjustable in height and wide in bearing range; and when the middlemass is changed, the airbag damper is maintained at a constant height through adjustment of the air pressure. The integrated adjustable double-layer damping module is high in integration degree, compact in structure and precise and controllable in height of the damping device, can adjust the middle mass in real time at the testing site, and achieves optimal damping effect.

Description

technical field [0001] The invention relates to the technical field of vibration and noise control and sensor measurement, in particular to an integrated adjustable double-layer vibration damping module. Background technique [0002] Mounting electromechanical equipment on vibration-damping (or isolation) devices can effectively reduce the vibrations it transmits to the environment. The double-layer (or floating raft) damping device is composed of an upper damper, an intermediate mass (or "raft") and a lower damper. Because of its excellent damping effect, it is widely used in many industrial fields, especially ships. It is widely used in electromechanical equipment. [0003] The intermediate mass of the double-layer damping device has a great influence on the damping effect. Generally speaking, the greater the stiffness and the greater the mass, the better the damping effect. The intermediate mass generally adopts two structural forms: one is the overall frame structure, ...
